Title: Focus position detecting device
Inventor: YAMAUCHI YOSHIHIKO
IPC: G03F9/00
Filed: 1985-10-07
Abstract: PURPOSE:To perform highly stable focus detection with high precision by photo detecting only reflected light from a body to be measured which is generated with two kinds of striped pattern light having a periodically varying light and shade part with arrayed photosensors through a cylindrical lens. CONSTITUTION:Illumination light becomes two kinds of stripe pattern light having the periodically varying light and shade part through striped pattern 3 for a front and a rear focus to illuminate the object body through a half-mirror 4a which is so sized and positioned as to exert any influence upon light from other optical systems. Then, the reflected light from the object body is transmitted through the mirror 4a and then the reflected light having a high SN ratio has the stripe pattern compressed lengthwise through a cylindrical lens 11. This compressed pattern light is photodetected by the arrayed sensors 7 with a good SN ratio without projection and only light and shade information on picture elements at the center part of the striped pattern is extracted so that the enlargement image width of either light or dark striped pattern coincides with the integral multiple width of the picture elements of the sensors 7. Therefore,the light and shade information is detected excellently without being affected by a difference in reflection factor, etc., due to the irredular state of the surface to be measured and the material, so that focus detection is performed highly stably with high precision.

Filed: 1984-10-24
Abstract: PURPOSE:To protect a tyre if it is punctured by increasing a ground clearance of a tyre which is placed in the lateral direction of the punctured tyre if the ground clearance of a tyre which is placed in the obliquely front or obliquely rear position of the punctured tyre is increased. CONSTITUTION:When a puncture detector 20 detects a puncture of a tyre, a puncture signal is sent to a receiving device 30. The receiving device then seeks for the punctured tyre from the front right, rear right, front left and rear right tyres 12, 14, 16 and 18. Suppose the front right tyre 12, for example, is punctured, the position of the tyre is input to a computer 32. The spring constant of the suspension unit of the punctured tyre is increased to restrain the punctured tyre from sink. The computer determines whether the ground clearance of the tyre 18 placed in the obliquely front or the obliquely rear position of the punctured tyre is increased or not. If the ground clearance is increased, the ground clearance of the tyre 16 which is placed in the lateral direction of the punctured tyre is increased. Such constitution can lessen a load which will be applied to the punctured tyre and protect the tyre.

IPC: G11B15/14
Filed: 1986-09-18
Abstract: PURPOSE:To prevent the titled device from being affected by the accuracy of drum assembling and mount arranging a head detection means at a position separated by a prescribed interval from the read reference position of the drum so as to detect the position of the head directly, thereby eliminating the need for timing adjustment. CONSTITUTION:A light emitting/receiving element 45 detecting the head 8 through the change in the light receiving quantity of a light receiving element 47 based on the difference of the reflectance between a window part 48 mounted with the head 8 and the other part for the light projected from a light emitting element 46 toward the side face of a rotary drum 16 is arranged at a position separated by a prescribed interval from the read reference position of the drum 7. Since a prescribed angle C deg. is given for the separation from the read reference position to the head recording start position, the angle B deg. between the light emitting/receiving element 45 and the head recording start position assumes a constant value. Accondingly, since the time after the light emitting/receiving element 45 detects the head 8 till the start of head recording become constant, the time is set by a delay circuit 37 to start the recording of the head 8 on a magnetic tape 100. Thus, the recording timing of the head 8 is always constant.

Title: Combustion detector for engine
Inventor: SHINYA YOSHIYUKI
IPC: G01L23/00
Filed: 1986-09-19
Abstract: PURPOSE:To exactly detect a combustion state by regarding a pressure by a prescribed crank angle, as a highest pressure, when it is decided that the highest pressure is caused by a compression pressure. CONSTITUTION:When a top dead center signal is inputted from a crank angle sensor 34, a combustion detecting part 41 reads a top dead center pressure sent from a pressure sensor 15 at this time, and a lowest value pressure sent from a lowest value holding circuit 45. In the same way, when the signal of 90 deg. after the top dead center is inputted, the highest pressure sent from a peak holding circuit 44 is read. Also, when it is detected by a crank angle signal that the crank angle is an angle set in advance, a pressure of this time is read. When the top dead center pressure and the highest pressure are equal within the range of an allowable value set in advance, the detecting part 41 regards the pressure which is subtracted with the lowest pressure from the pressure of the crank angle, as the highest combustion pressure, calculates a variation rate with regard to this highest combustion pressure, and outputs it to an air-fuel ratio control part 46. When the variation rate is high, the combustion is unstable, therefore, the control part 46 calculates the air-fuel ratio so that the air-fuel ratio becomes low, and outputs a fuel jet pulse to a fuel jet valve 8.
